Aston Sandford is a small village and civil parish in Buckinghamshire, England, about 1 mile (1.6 km) east of Haddenham and 4 miles (6.4 km) northwest of Princes Risborough.

It is in the civil parish of Kingsey within the Buckinghamshire Council unitary authority area.

The "Aston" part of the toponym is derived from the Old English for "Eastern Estate".

At the time of the Domesday Book in 1086 the village was known as Cold Aston, and both it and Haddenham were owned by the same manor, suggesting that Aston got its name from being the farming estate to the east of Haddenham.

[2] However, the building was so extensively restored and reworked in 1878 that it is difficult to date any of its features with certainty.
